Summary Information

In 1998, the United States Congress designated the I-25 Truck Safety Improvements Project (I-25 TSIP) to support transportation improvements in the State of Colorado. This congressionally designated project was intended to improve transportation efficiency, promote safety, reduce emissions, improve traveler information, enhance alternate transportation modes, promote tourism and build on existing Intelligent Transportation Systems (ITS). The local evaluation report assessed how well the project met the stated goals and objectives. Among the numerous projects associated with this project, the Colorado DOT added three additional locations for trucking ports of entry (POE) automation under the goal of "addressing ITS infrastructure deficiencies."

The throughput of goods, savings to the private sector, and emissions impacts can be directly measured from the automation equipment installed as part of this project. POE automation included installation of weigh in motion (WIM), automatic vehicle locators (AVL), and associated computer and communications equipment necessary to perform electronic credentialling.


PrePass™ allowed subscribers to bypass inspection stations if their credentials were in order. Evaluation data indicated that the automated system saved approximately 8,000 vehicle hours of delay per month.
